In addition to overloading constructors with different parameters, we can overload constructors with default parameter values, as well. For example: class Circle { private: double radius; public: Circle() { radius = 1.0; } Circle(double r) { radius = r; } Circle(double r, double x, ...
// overloading class constructors #include <iostream.h> Class CRectangle { int width, height; public: CRectangle (); CRectangle (int,int); int area (void) {return (width*height);} }; CRectangle::CRectangle () { width = 5; height = 5; } CRectangle::CRectangle (int a, int b)...
Constructor overloading is a concept of having more than one constructor with different parameters list, in such a way so that each constructor performs a different task. For e.g.Vectorclass has 4 types of constructors. If you do not want to specify the initial capacity and capacity incremen...
Constructor Overloading in C++ In C++, We can have more than one constructor in a class with same name, as long as each has a different list of arguments.This concept is known as Constructor Overloading and is quite similar to function overloading. Overloaded constructors essentially have t...
If you’re coming from a language such as Java or C#, the concept of constructor overloading is a pretty common one. But as a refresher in say C#, we can overload constructors like so : class MyClass { public MyClass(string value) { this.value = value; } public MyClass(int ...
Inside the main function, create objects by passing the different number of arguments to test the functionality of the concept of constructor overloading. C++ program to create a class with two constructors Consider the below example to create a class with two constructors in C++. ...
(a:Int, b:Int) :this() { println("Secondary Constructor With Two Parameter [$a, $b]") } }//Main Function, Entry Point of Programfunmain(args:Array<String>){//Create instance of class , with Primary ConstructorConstructorOverloading(100)//Create instance of class,//with no argument ...

Overloading with the zero-argument constructor However, it might also be common in the application to create an origin point at coordinates (0,0). In this case, the developer might provide a zero-argument constructor that lets a developer create a point with 0, 0 as the defaults. ...
